Hi, so I connected USB 1 on the imx 8 as dedicated USB 2.0 port for serial download. ID is NC , and D+ and D- is goes to a usb mini connector(all protection in place). Vbus from connector goes through a 1k resistor to USB1_vbus.
I also have boot mode0 pin pulled up by 10k to high and boot mode1 pulled down to GND.
I however cannot get windows or linux to recognise the USB port. It has just been powered up with no code and was planning to use the uuu utility to load firmware into an emmc device but I am unable to do that if windows can't see a new device connected. Am I missing something? Does this work with usb2.0 or only usb 3.0? any help will be greatly appreciated.
I am using a 5pin USB micro connector, does the ID pin on the connector need to be connected?
